My invention relates generally to abraders and particularly to anabrader intended for application to the human epidermis for the purposeof removing thickened or calloused areas.

It is among the objects of my invention to provide an abrader which isuseful for ,abrasively removing or reducing a thickened area of thehuman epidermis.

It is a further object of my invention to provide an abrader which willoscillate an abrasive wafer at a high rate of speed.

Yet another object of my invention is to provide an abrader which isconvenient and easy to hold in the hand in order to apply an abrasivewafer connected thereto, to the human epidermis for the purpose ofminimizing thickened areas thereof.

These objects and advantages as well as other objects and advantages maybe attained by the device shown by way of illustration in the drawingsin which:

FIGURE 1 is a vertical elevational inside view of one of a pair ofshells which when assembled together form a housing for the abrader;

FIGURE 2 is a view of a shell complementary to the shell shown in FIGURE1, with the electromagnet and armature mounted therein;

FIGURE 3 is a side elevational view of a cap coopera- Y tivelyengageable by the pair of the shells, and constituting a closure for thetop of the housing;

FIGURE 4 is a top plan view of the cap;

FIGURE 5 is a side elevational view of the disc, partially sectioned,for mounting an abrasive wafer, with the abrasive wafer adhesivelysecured thereto;

FIGURE 6 is a top plan view of the disc with the abrasive wafer appliedthereto;

FIGURE 7 is a side elevational'view of the assemblage.

Persistent irritation of the humanepidermis in limited areas produces anatural response in the nature of a defense mechanism: This response isthe formation of a callous or toughened and thickened area on theepidermis. This area is more resistant to damage by contact, than theuncalloused epidermis. The formation is commonly experienced on thehands by those who perform hard manual labor, and upon the feet by thosewho walk extensively, or who wear shoes that are not properly fitted;

The calloused area may persist for a long period of time beforesloughing oli, even though it has no longer any implement can bedangerous unless conducted with skill and precision. On the other hand,the removal of callouses by abrasion proceeds slowly and can be;conducted by the unskilled without danger. An abrader for this i purposeis shown by way of illustration herein.

Referring to the drawings in detail, a pair of complementary shells 11,12 are shown in FIGURES 1 and 2.

of the shells '11, '12 areprovided with 'semi-circular openings in whicha cord guide l5 canibejseated. Acord 16 3,169,536 Patented Feb. 16, 1965can be introduced through the cord guide 15 into the housing formedby'the shells 11, 12. Mounted in the housing is an electromagnet 17. Aresilient defiectable armature 18 is mounted on a bracket 19 so that thearmature 18 will be responsive to the electromagnetic lines of forceoriginating in the magnet 17. This deflec able armature has=a top,L-shaped portion 20, which extends transversely in the shells 11, 12near the cap 23. The bent over portion 20 is provided with a rigidlyattached stem 21. This stem extends out of the housing 22.

The housing is enclosed at its upper end by aca'p .23. The shells, 11,12 have inwardly extending walls 24 near their top edges'25. These walls24, 24 do not meet, but have a gap permitting the protrusion of the stem21 from out of the housing. The upstanding portions 25 of the shells 11,12 above the walls 24,24, are provided with a small domed enlargement26. This enlargement engages an aperture 27 in the cap 23, when theshells 11, 12 are assembled together with the cap between the portions25. 28. The walls 24 on each of the shells 11, 12 have an upstanding rib29 that enters the slot 28 in the cap 23. Thus, when the shells 11, 12are bolted together, the cap 23 is firmly secured in place. The cap 23is provided with a generally oval, elongated, top slot 30, throughwhichthe stem 21 extends. Mounted on the stem is a disc 31. The disc 31has a socket enlargement 32 having an interior bore 33. The bore 33 ispress-fitted onto the stem 21. Adhesively secured to the top of the disc31, an abrasive wafer 34 is attached. Since the armature is magneticallydeflectable with respect to the magnet 17, 1

when the magnet is energizedby an alternating current, the armature 18will oscillate at a high rate of speed and the abrasive wafer 34 will becaused to describe a reciprocating movement. When the wafer 34 isapplied to the human epidermis while it is reciprocating, a callous towhich it is applied will be abraded and reduced in size.
